Sponsor The Tool: Find customers by sponsoring the tools they already use

Hey Product Hunt 👋 I’m Lionel, the maker of Sponsor The Tool. I built it because most free calculators and converters have one of two problems: they’re buried under unrelated ads, or they disappear once the result is delivered. Meanwhile, businesses spend heavily reaching people who may not need them yet. Sponsor The Tool connects those moments. Someone uses a tool, gets an answer, and then sees one clearly labeled sponsor that can help with the next step. Today’s launch includes 227 tools across 13 categoriesl,from finance and business to health, files, marketing, and developer utilities. Sponsors can reserve one tool or an entire category and track views, results, clicks, and referring pages. The rule is simple: one tool, one relevant sponsor. No wall of banners and no auction of attention. I’d especially value your feedback: • Does a recommendation after the result feel useful or intrusive? • Which tools or categories should we prioritize? • What would make a sponsorship worth testing? Thanks for taking a look. I’ll be here answering questions and listening to feedback.
